Summary: The surgical reconstruction of congenitally missing or malformed ears is challenging and involves complicated surgeries. It is easier to reproduce compromised ear features with a prosthesis. This article describes the prosthetic reconstruction of 3 patients who had received failed or suboptimal surgical reconstruction of their missing or deformed ears. Challenging characteristics included limited soft-tissue availability, skeletal hypoplasia with prominent concavity defect, and bilaterally missing ears with abnormally low hairline. Three-dimensional planning and stereolithography printing were used for ideal implant locations and mirror image reproduction.

Summary: This study investigated the social perception of microtia and the impact of reconstruction on socially perceived attributes. The results showed that faces with microtia ears were perceived as less friendly, less healthy, and less successful compared to faces with normal ears, while there were no significant differences in socially perceived attributes between faces with normal ears and faces with reconstructed ears.

Summary: This study explores the author's experience with long-term follow-up analysis of secondary procedures in patients with unsatisfactory initial microtia reconstruction. The results suggest that using autogenous costal cartilage framework can achieve good aesthetic outcomes for patients undergoing secondary reconstruction surgeries.

Summary: This study investigated the safety and efficacy of using intense pulsed light (IPL) for depilation in congenital microtia patients during reconstruction treatment. The study found that hair density reduction and effectiveness were higher in the expander group compared to the non-expander group after 3 treatments. Adverse effects observed were folliculitis and blisters. IPL depilation is a safe and effective method for photo-epilation during ear reconstruction using tissue expander.

Summary: The growing interest in auricular anatomy stems from two main areas of research: autologous ear reconstruction in medicine and human detection and recognition in surveillance and law enforcement. Systems for ear analysis vary based on the type of input data, acquisition tools, and algorithms used. While segmentation and recognition of the ear from the face is well-discussed, detection and recognition of individual anatomical elements remains an area that has not been extensively studied.

Summary: The posterior auricular artery flap reconstruction of the retroauricular sulcus in microtia repair is a valuable alternative to current techniques, providing an ideal skin color and texture match and potentially enhancing overall results through improved vascularity.

Summary: This study aimed to analyze the therapeutic choices patients make after consultation concerning their auricle and/or hearing. The results showed that most patients with a congenital etiology chose to wait or decided against auricular reconstruction, while patients with acquired etiologies mostly opted for reconstruction by a prosthesis. Patients or their caregivers were very satisfied with their choice, regardless of whether this implies reconstruction or no reconstruction, which emphasizes the importance of shared decision-making and thorough counseling.

Summary: The study modified the conventional crescent cartilage block by sculpting a concavity at its posterior surface, which effectively improved the retroauricular contour and aesthetic outcomes for patients. The concave crescent-shaped block can enhance the auriculocephalic sulcus contour while ensuring ear projection.

Summary: This study systematically reviewed clinical studies on auricular reconstruction in microtia and compared the efficacy and safety of the flap pocket method and the expansion method. The results showed that the flap pocket method had better patient satisfaction, lower incidence of complications, and shorter treatment period compared to the expansion method.

Summary: This article reviews the development, current application, and research progress of cartilage tissue engineering in auricular reconstruction, particularly focusing on the usage and creation of biomaterial scaffolds. It also highlights the development and selection of various types of seed cells and inducing factors to stimulate chondrogenic differentiation in auricular cartilage. Despite facing challenges and the need for long-term evaluation, the research directions of biomaterials as an alternative to autologous cartilage in ear reconstruction are discussed to benefit the transformation and clinical application of cartilage tissue engineering and biomaterials in microtia treatment.

Summary: Microtia is a congenital condition that can affect hearing, speech development, and cosmesis. A non-surgical prosthesis called 'Ear Glove' has been effective in providing aesthetic results for pediatric patients with microtia.

Summary: This study described three minor modifications to the sculpting of the auricle framework, which improved the appearance of the reconstructed auricle and laid a solid foundation for subsequent operations. Through a retrospective study of congenital microtia patients, it was found that these modifications resulted in a more satisfactory auricle appearance and improved patients' satisfaction.
